After all, doesn't XMPP still require use of jabber:client or jabber:server as namespaces for stanzas in XMPP streams? My original email cited an out-of-date RFC, but I did check back later: [[ Definition of XML Stanza: An XML stanza is the basic unit of meaning in XMPP. A stanza is a first-level element (at depth=1 of the stream) whose element name is "message", "presence", or "iq" and whose qualifying namespace is 'jabber:client' or 'jabber:server'. ]] -- http://tools.ietf.org/html/rfc6120#section-4.1 In light of this, my take is that jabber: is a current but very limited URI scheme, defining just two URIs (jabber:server and jabber:client) for use in XMPP streams. No other URIs or uses for this scheme are sanctioned. #g -- > http://tools.ietf.org/html/rfc4395#section-4 > > On 11/26/12 1:27 PM, Joe Hildebrand (jhildebr) wrote: >> Looping the XMPP wg list.
